PUMP.

Application filed December 6,1924. Serial 1a,. 754,417.

' for instance, at the bottom of a mine shaft.

' An object of the invention is the provision of an improved construction in a pump of easily handled. p v i A further object is the provision of regulating means whereby the speed of the flow of water may be regulated to agree with the speed or the jack.

A further object is the provision of a pump of this character which'may be. operated in a suspended position above the water level or in a submergedposition.

In the accompanying drawings, I have shown one embodiment of this invention. In this showing:

Figure 1 is a plan view of the cylinder connected to the prime mover or jack and its associated parts,

Figure 2 is a side elevation of the pump cylinder adapted to be mounted in the mine shaft, 7

Figure-3 is a transverse vertical sectional View online 33 of Figure 1,

Figure 4 is a vertical sectional 'view 01. the pump cylinder,

Figure 5 is a transverse sectional view on line 5-5 of Figure 4, and,

Figure 6 is a plan view 01 the pump cylinder with the cover of the valve chest and the valves removed. 1

Referring to the drawings, the reference numeral 1 designates generally a source of power which may be of any type of prime mover. A connecting rod 2 is adapted to be reciprocated by the prime mover, and this connecting rod is connected to a piston (not shown) arranged in a cylinder 3. The cylinder is provided with outlets 1 at opposite ends, which are adapted to be connected to pipes 5 extending vdownwardly, forming a pair of water columns.

this character that is compact in form and Referring to Figure 3 of the drawings, the ends of the cylinder are connected to pipes 4: extending upwardly and communicating with a T 5. Valve casings 6 are arranged in horizontalarms 7 and these valve casings are provided with check valves 8, which permit flow of water toithe pipes 1f but prevent it from flowing in a reverse direct-ion. pipe 9 communicating with a ,reservior 10. The pipes 4 are furtherprovi'ded ith'r'elief valves 11, having suitable handles 12 to permit manual operation.

On oneside of the cylinder, there is provided a pair of pipes 13" (see Figure 1), connected to elbows 14. These eibewsm-e connected to a transverse pipe 15, and a T-joint 16 is a ranged intermediate the ends of the pipe 15. Check valves 17 are arranged in this pipe to permit flow or water inwardly to the T-joint 16. The pipe 15 is connected outwardly of each check valve to a pipe 18 andthese pipes are connected to each other by a horizontal pipe 20. Intermediate the ends of the pipe, there isprO- vided an equalizing valve 21 normally held in closed position by a spring (not shown) but which is actuated automatically by a difference in pressure in the pipes 18 and the casing of the valve is co'nnected'to the T-joint by a pipe 22. Outwardly opening check valves 23 are arranged on eachfsi'de to receive connecting members 31, which are connected to the lower ends of the water columns and a piston 82 is arranged therein. A partition 33 separates the power cylinder from the pump cylinder and the pis- The T. is connected to a vertical 7 elbows 19, which are in tu'rn connected to A ton is provided with a piston rod 84, passing through this partition. As shown, 'a

suitable packing 35 may be provided in the partition to receive the piston rod and preventleakage. A 0011 spring 36 1s secured to one end of the cylinder and this i on its seat by a spring 49.

spring is adapted to be engaged by the piston to take up end thrust.

, The pump cylinder is provided with a piston 37 mounted on the other end of the piston rod 34, and adapted to be moved by thepiston rod. The outer end of the pump cylinder is also provided with a spring 86 adapted to be engaged by the piston 37 to take up end thrust; when the pistons are traveling in the opposite direction. the cylinder, the pump is provided with a pair of pump chambers 38, separated from each other by a partition 39 and connected to the opposite ends of the pump cylinder by passages 40. An inlet chamber 41 is arranged beneath the pump chambers and communicates with an inlet pipe 42. The pump chamber and the inlet chamber are separated from each other by a horizontal wall 43, and

this wall is provided with a plurality of valve openings a l. Each of these enings is provided with a transverse mem er 45, having a central opening 4:6 for the reception of a valve stem 47. A valve 48 of the disk type is arranged on the lower end of each valve stem and is normally retained The valves are adapted to open inwardly by suction existing within the amp chamber. The pump is further provided with an outlet chamber 50, separated from the pump chambers by a horizontal Wall 51, and a vertical wall 52. The horizontal wall is provided with a plurality of openings 53 having transverse members 54. These transverse members are provided with openings 55, adapted to receive valve stems 56. Disk valves 57 are mounted on these stems and are normally retained in closed position by means of springs 58. These valves are adapted to be opened by pressure within the pump chambers.

The outlet chamber communicates with an transverse wall 39 forms a pair 0 outlet pipe 59.

In operation, the cylinder 27 is first located in the mine and the columns 5 attached. The pet cocks 11 are opened and water supplied to the reservoir until the system is filled. When water begins flowing from the pet cocks, so that all air has been expelled, the pet cocks are closed and the reservoir is filled with water. The prime mover is started to actuate the piston int-he cylinder 3 and movement of the piston alternately causes an increase and decrease in pressure in the columns 5. This change of pressure reciprocates the piston 32 in the power cylinder 28 and the piston 37 likewise reciprocates, being connected to the piston rod 34:. The springs 36 on the opposite ends of the cylinders are engaged by the pistons to prevent end thrust. -When the piston 37 reciprocates in the pump cylinder, the pump acts in the same manner as an ordinary double-acting suction pum The pump Above chambers and as the piston moves away from either end of the cylinder, a partial vacuum is created in the pump chamber through the passage lO. This opens the inlet valves 4:8, admitting water from the inlet chamber The return movement of the piston creates a pressure in the pump chamber and the outlet valves 57 are opened to deliver the fluid to the outlet pipe The inlet and outlet chambers e'fl and 50 both extend the full length of the two pump chambers.

During the operation of the device, the reservoir is maintained full of water and any decrease inthc supply of water in either column is compensated for from the reservoir. The check valves 8 prevent the water from returning to the reservoir when pressure is built up in either of the columns. The regulating mechanism arranged on one side of the cylinder permits the stroke of the piston to be regulated according to the stroke of the jack. The valve 21 is em ployed for this purpose. The pipe connec tion 25 and the valve 26 are employed when starting the device at a high rate of speed, the valve 26 being opened and slowly closed to act as a clutch to secure the proper regulating action through the regulating systern. l

It is to be understood that the form of my invention herewith shown and described is to be taken as a prcierred example of the same, and that various changes in the shape, size, and arrangement of parts may be re sorted to without departing from the spirit of the invention or the scope of the subjoined claims.
